method of assembly and the di?erent component parts
of the lighter will be more readily understood.
The decorative outer case for the lighter, generally
referred to by the letter A, is made of metal, plastic or
other suitable material. The general con?guration of
the case A is illustrated in FIGURE 12, and the top
plan view thereof is shown in FIGURE 1. The top of
the case has a removable cover 10 with an aperture 11
This invention relates to a simpli?ed and compact 10 formed therein immediately above the discharge valve
of the lighter. The cover 110 has an outwardly extending

vaporized fuel escaping through the discharge valve.
Heretofore all such attempts have resulted in devices
which are exceedingly large or which contain complex
valve structures and, as a result, they are inefficient and
tend to mal-function.
In our device we have invented an effective metering
The case A has a removable base 14 thereon which is
attached to the case by means of a screw 15. A metallic
plate 16 ?ts within the ?anged extension 17 of the base
14, and the holding screw 15 is seated against the plate
16. Disposed between the plate 16 and the upper portion
of the base 14, is an annular washer 18, which serves
as a spacer between these elements.
The screw 15 is

periods of time.
Another object is the provision of a simpli?ed positive
action discharge Valve which can be adjusted to vary the
height of the ?ame.
Another object is the employment of structurally rein
forced parts, designed for minimum space requirements,
and which will result in a ?nished product of a size gen
erally acceptable for its intended purpose.
Another object is the provision of a pyrophoric lighter
with a simpli?ed transfer valve to permit refueling the
lighter with gas which is in liqui?ed form when under
pressure, but which will vaporize when exposed to the
atmosphere.
FIGURE 4 shows an enlarged detailed section of the
discharge valve, generally referred to by the ‘letter B,
which is adjustable to meter the amount of vaporized
fuel released from the lighter. Through the simple ad
justment of the discharge valve the height of the ?ame
can be varied to suit the requirements of the user. The
35 discharge valve B is disposed within the cylindrical tube
22 which extends ‘downwardly from the under surface of
the lighter cover 21. In the device illustrated, the cylin
drical tube 22 is cast integrally with the cover 21 and its
inner surfaces will be described hereinafter. The bottom
